AliasedColumn

Related Doc: package ast

sealed trait AliasedColumn[A] extends Column[A] with CellExtractor[ResultSet, A]

A column that has an alias associated with it.

The columns selected by a relation must all have aliases. This is how we address them in the JDBC ResultSet:

SELECT a as a_alias, b as b_alias, c as c_alias FROM ...
